FREE Expert Solution

Recall that ionic radius is the size of an ion. The trend for ionic radius is as follows: it increases from right to left and down a period in the periodic table. Ionic radius also increases with increasing number of electrons


Li +

  • Li: 3 e→ lost 1 e- → 2 e-

Mg2+

  • Mg: 12 e→ lost 2 e- → 10 e-
